Molecules as circuits

The Kondo effect can improve a molecule’s conductivity

The progressive miniaturization of electronic devices requires the creation of increasingly small circuits. With traditional technology, this miniaturization is hampered by the limits imposed by physics, but some have thought of using molecules as circuits.

If molecules are to be able to do this efficiently, they need to improve their poor conduction ability. In a study published in PNAS, a team of researchers featuring Ryan Requist, Erio Tosatti and Michele Fabrizio of SISSA shows how the Kondo effect can improve the conductivity of some magnetic molecules.
